BOX-STAPLING MACHINE.

SPECIFICATION forming part of Letters Patent 0. 576,382, dated February2, 1897. Application filed February 19, 1896. Serial No. 579,883- (Nomodel.)

To (tZZ whom it may concern:

Be it known that I, FRIEDRICH THEODOR SPEOKBOTEL, a subject of the Kingof Prussia, Emperor of Germany, and a resident of Hamburg, Germany, haveinvented an Improved Box-Stitching Machine, of which the following is aspecification.

This invention relates to a machine for making wooden boxes of which thesingle sides are joined by means of wire staples. As the most essentialparts of the machine are to be mentioned the wire feeding and cut-offapparatus, the apparatus for bending the wire staples and for drivingthem through the wood to be joined, and the apparatus for clenching theprojecting wire ends. All these apparatus are so alternately connectedwith each other that they always come to action in the proper successionwhen the machine is set to Work by means of a foot-treadle.

The machine is illustrated in the accompanying drawings, in which Figure1 shows the machine in side elevation, the wire-feeding apparatus havingbeen left away; Fig. 2, the same in front elevation; Fig. 3, thewire-feeding apparatus in side elevation; Fig. 4, a front view of theso-called wire-head, the covering-plate having been removed; Fig. 5, aview of the covering-plate turned over at an angle of one hundred andeighty degrees; Fig. 6, a sectional view of the wire-head withcovering-plate 011 line A B of Fig. 4; Fig. 7, the apparatus forclenching the projecting wire ends in front elevation,the covering-platehavingbeen removed Fig. 8, a detail of this covering-plate; Fig. 9, asectional View on the line 0 D of Fig. 7; Fig. 10, the mechanism fordriving the wirefeeding rollers; Figs. 11 and 12, the plates guiding thewire while it is being bent and driven through in elevation and plan,and Fig. 13 the apparatus for adjusting the machine for differentthicknesses of wood.

In the frame a of the machine two axles of rotation b and c arearranged, to which the levers d and f are keyed. Of these the former, d,serves as a support for the feeding, the cutting off, the staple-bendingapparatus, and the apparatus for driving through the staples, while tothe latter, f, being movable with regard to the former, d, the parts formoving the different apparatus are connected. The

levers d and fare moved by means of the con necting-rods g and it, thesecatching with their pins '1: and 7a, which for sake of decreasing thefriction may be provided with rollers, into the slots Z and m of thedisks 0 and 19, connected with each other and arranged turning aroundthe axle 41. Of the disks one is provided with an eye q, so connectingit with the foot-treadle, serving to work the whole machine. Below thelevers the saddle r projects bayonet-like, within which the apparatusfor clenching the projecting wire ends is arranged. This saddle has theform of a roof and serves as a support for the work.

Of the different apparati serving for the different operations thefeeding apparatus shall first be more particularly described accordingto the succession of the operations. This apparatus consists of twofeed-rollers s, set in a case laterally arranged at the head of thelever cl and geared together by means of toothed wheels, and of theguide-plates t, arranged before and behind the rollers and provided withgrooves for the wire. On the axle u of the one roller a ratchet-wheel ois fastened, into which the click w of a lever at, turning around theaxle it, catches. The lever a: is so connected by means of theconnecting-rod y with lever z, fastened to axle b, that when the axle bis turned around a certain angle the ratchet-wheel 'u is turned on onetooth. The axle of the driven roller 8 turns around a horizontal pivot aand is pressed by a spring 1) against the drivingroller, so enabling thewire to be entered between the rollers at the beginning of the operation. As already mentioned, the feeding apparatus is fastened bymeans of an angular plate to the front end of the lever (Z. This frontend or wire-head is case-shaped and contains a U-shaped slide-block 0,provided with two cutters d at its lower end, of which the left one,Fig. 4, is sharp and serves as cut-oft for the wire, together with thecuttingblock 9, being the continuation of the guideplates 75 andfastened to the cover f. The slide-block bears on its back two tappetsh,

between which the three-armed lever t", turning on a pivot in lever cl,rests with its arm 70, while the second arm Z catches by means of apivot 17?. into the slot n of the pressure rod 0, connected to the leverf. Below the lever d a horizontal rod 1) (the so-callcd bending-block)is arranged, guided partly by a block fastened to the lever d, partly bythe wire-head itself, and is always pressed forward by a spiral spring.This rod is provided at its front end with a groove q, forming thecontinuation of the groove in the cutting-block g and preventing thewire from deviating while being introduced into the wire-head, the roditself serving, together with the cutters cl, to bend the staples. Thethird arm rf of the above-mentioned lever i, catching into a notch s ofthe rod 19', serves to move this rod backward. lVit-hin the U- shapedsliding block 0 there is arranged the sliding stamper i", connected withthe lever In the lower end of this Stamper If two narrow plates u arefastened, turning around a pivot and serving to drive the staplesthrough the box-wood. In order to prevent the wire from laterallybending or deviating, two guide-plates 'u are arranged in the lower partof the wire-head provided with a corresponding groove the wire being sokept from deviating laterally.

The apparatus for bending the staples and driving them through the woodhaving thus been described, there remains only the mechanism arrangedwithin the saddle r for clenching the wire ends projecting through thewood. This mechanism is formed by two tongues or, turning around thepivots y of a plate 2, arranged vertically movable within the saddle andcatching with pins a in the slots b of the saddle cover-plate o. Thetongues are moved by means of an angle-lever d arranged turning withinthe saddle and catching with an arm into the slot f of the plate .2,while the second is connected with a rod g the back end of which lies inthe course of a head 712 on the disk 19, the rod itself being alwaysdrawn back by a spiral spring For sake of equally distributing thesingle staples along the different lengths the saddle r is provided withadjustable ledges k and 1".

Lastly, an apparatus is provided for ad j usting the machine fordifferent thickness of wood, as else the bending of the staples couldnot be correct. This consists of a hand m eccentrically arranged on theaxle a. By turning this axle in the direction of the arrow the levers dand f are more or less advanced toward the saddle.

The action of the machine is as follows: The end of the wire rolled on areel next to the machine is entered, after having pressed down the lowerfeeding-roller against the action of the spring 1'), through thefeed-channel so far between the rollers until it stops on the rightside, Fig. 4. Then lay the woods on the saddle as they shall be joinedtogether and move the disks 0 and p upward around the axle n by means ofthe foot-treadle. (Not shown in the drawings.) The pins 2' and 7; soslide in the slots Z and on, moving the connectingrods 9 and h andturning the axles b and 0, whereby the levers d and f are lowered. As

soon as the front end of the lever d reaches the saddle, respectivelythe wood lying on it, the further motion of the lever 61 stops, as thepin at this moment reaches the point a of the slot Z from where the slotis concentric to the axle n. The lever f, however, is lowered onfarther, the slot at of pressure-rod 0 coming into action. This causesthe three armed lever t" to turn, so lowering the sliding block 0 and atthe same time the cutters (2. Consequently the left side cutter, Fig. 4,sliding along the cutting-block 9', cuts off the wire, guided by thechannel in the cuttingblock, whereupon the inward cutter-surface,together with the rod 1), bends the wire ends and so makes the staple.During this operation the stamper t, with the staple-drivers a, has beenpressed down by further lowering of the lever f, and now thestaple-drivers catch the wire and drive it through the wood, as therod 1) has been drawn back by the lever '6', and the guide-plates 1;,with their grooves 20, prevent a deviation. In the last moment of theupward motion of the disks, when the slot on becomes concentric to theaxle n, the head 72/2 reaches the rod 9 and turns the angle-lever dHereby the plate 2', with the clenching-tongues a is raised and thelatter smoothly,turn down the proj ecting wire ends, whereupon thestitching is completed.

Vhile for the first stitching the wire must be entered by hand, thefurther feed of wire is automatic. On the levers cl and f being loweredalso, the lever .2 has been lowered and the lever turned in thedirection as shown by the arrow, whereby the click falls into the nextfollowing left tooth of the ratchet-wheel. After the first stitchinghaving been completed the foot-treadle is released and is drawn by aspring, stretched on pressing it down, back into its original position,the different disks and levers moving back at the same time. On .2 somoving back, the click turns the ratchet-wheel 0) one tooth forward, andthe wire necessary for making the next staple is entered into themachine.

As the shape of the machine, as more particularly described in drawingsand description, is such as is required for stitching the sidestogether, it may easily be understood that by a simple change of thesaddle the same apparatus can be used for stitching on the bottomwithout changing the principle of the machine. Furthermore, the wholemechanism may be arranged double or triple in order to drive in two orthree staples at a time. Though the machine hereby getssomewhatcomplicated the multiplying requires no principle change.

lVhat I claim is- 1. In a box-stitching machine, the combination of acutter with a lever f, a slotted rod 0, connected thereto, and a levert", engaging the slotted rod and adapted to actuate the cutter,substantially as specified.

2. In a box-stitching machine, the combination of a Wire-feed with acutter, a Stamper engaging the same, a bending-rod, and a threearmedlever adapted to actuate both the cutter and the bending-rod,substantially as specified.

3. In a box-stitching machine, the combination of a pair of levers f, d,with a stamper connected to lever f, a Wire-feed, cutter and bending-rodconnected to lever (Z, and a threearmed lever oscillated by lever f, andadapted to actuate both the cutter and the bending-rod, substantially asspecified.
